About E26.8

E26.8 is the ICD-10-CM diagnosis code for other hyperaldosteronism. It belongs to category E26 (hyperaldosteronism), block E20-E35 (disorders of other endocrine glands) and chapter 4 (endocrine, nutritional and metabolic diseases). It is a header code, so it can't be reported by itself; one of its 2 subcodes must be used instead.

Within E26, choose E26.8 (Other hyperaldosteronism) only when documentation doesn't support a more specific option: primary hyperaldosteronism (E26.0), secondary hyperaldosteronism (E26.1) and unspecified (E26.9).

To report this condition, pick the subcode that matches the documentation: E26.81 (syndrome) and E26.89 (hyperaldosteronism).

It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.
